imputation' flied Marchio, 1927. serial No. 174,118.

The present invention relatesto improvements in beaters adapted to be used for culinarypurposes, such as whipping` crearnand` e Us. f f, l

gtrlhe primary object of the present invention is to provide a new*` and improved beater, which is simple, `sturdyand inexpensive in construction, and which is adapted to apply an extensive and effectual `shearing force on the liquid. 'p

A more specific object resides m1 the provision of a frame vwhich is formed out of a single piece of metal, which can be cheaply and quickly manufactured, and which has baille means and shearing edges for increasing the bearing action. f

Further objects and advantages will become apparent as the description proceeds.

ln theaccompanying drawings, Figure 1 is an elevational :view of a beater in accordance with our yinven- Fig2is'a verticalfsecti'on taken alonglme 2-2`of Fig. 1.-l 1 i l y Fig. 3 is a horizontal section taken along line33 of Figl;

While the invention-is susceptible of vari-- ous modifications and alternative constructions,- we have shown fin 1 the. drawings and will herein describe indetail `thepreferred embodimentJ thereof, but it is to be understood that we `do not thereby intend to limit the invention to the specific forni disclosed,

but intend to cover allfmoditications and alternative constructions falling within the spirit and scope of the invention, as expressed in the appended claims. l Y l; i

Referring to the preferred embodiment ol our invention shown 'in the drawings, the beater comprises a vertical iframe 10 which is formed out of a single bar of metal. The bar is bent to form a 4vlil-'shaped bracket 11 having upper and lower parallel. arms 12 and 13. Any suitable handle may be provided for the frame. In the presentinstance the bar is bent above the arm 12 to form a handle 111 integral with the frame. From the arm 13, the bar is bent downwardly to form a side frame member 16. Preferably 'the mem-- ber 16 is slightly inclined outwardly from the arm 13 so as to provide strength and to prevent undue flexure of the frame by pressing downwardly on the handle 14k. The lower end of the member 16 is slightly bent to form a vertical baille section 17. The lower.

end of the bar is bent lsubstantially at right angles to the section '.17 .to form a bottom member or bar 18.` Preferably, the bottom member 18 is curved concave upwardly. The

free end `of thebottommember 18 "is struck `up generally at right 'anglesA to formA abaie arm or plate 19 opposite the baille section 17.

`Rotatably mounted in the arm 13 andthe bottom member or strip 18 ,is a vertical shaft 20. 2 A pinion `21 is fixed on the upperend of the shaft 20, and preferably is `secured thereto by upsetting the metal on the end of the shaft, as shown at 22. The upperend lof the shaft 20 is reduced in size by this offsetting of the metahand is journaled in a hole 23 in the arm 13. To hold the shaft 2O in vertical position, its upper end Ais riveted. In mesh withrithe pinion 21. is a relatively large gear 24ywhich is journaled onta stud 25 onthe bracket 11, and which is provided with a suitablehandle26. Preferably, the

stud 25 is riveted to the bracket. 11. Iii-the y present instance, the. gear 2.11 has a plurality of holes or slots 27 stamped therethrough neXt to its periphery and meshing with the pinion 21. 1

A fan or propeller member 28 is rigidly fixed on thelower end of the shaft 2O directly over the bottom member 18 and between the baille section 17 and the baille arm 19 `and `is provided with aplurality of 4inclined blades, vanesor fins 29 inclined upwardlyand forwardly with respectto the direction of rotation, so as to apply a downlward thrust to the liquid. Aln the present instance, the propeller member is` secured to the shaft 20 by off-setting the metal atthe lower end of theflatter, as indicated at 30. The reduced lower end of thek shaft20 tits into a hole V3l in the bottom strip 18, and is vriveted vto hold the shaft in vertical position.

and are formed with sharp edges instead of` being rounded, and when the propeller member 28 and the bottom member 18 are positioned closely together.

The baille arm 19, struck up from the bottom strip 18, is inclined rearwardly with respect to the direction of rotation of the propeller member 28, and is twistedto present .a surface laterally inclined outwardly and rearwardly 4to the swirling liquid.

In use, the b'ottomstri'p 18 rests on the bottom of the container for the liquid (not shown). The propeller member 28 has aH sharp inherent shearing action, This action is increased by the tendency of the propeller member 28 to force the liquid into the conlined space betweenit and the bottom of the container. The propeller member 28 also serves to idirectthe liquid against the baille section 17, the bottom strip 18 andthe baiiie arm 19 which impede the swirling liquid. The inclined baiile surface of the arm 19 serves to shear the liquid, to raise the same by virtue of its area so as to aerate the liquid, and to direct the same toward the vortex. It will be evident that we have provided a beater that is simple, sturdy and inexpensive in construction, and that can be easily and quickly. manufactured.

'We claim as our invention:

1. A beaterA having, in combination, a frame member bent to comprise an upper bracket having spaced horizontal arms, a side member inclined'from the lower Aarm and forming a baiile section at its lower end, a horizontal bottom strip underlying said lower arm and being .concave upwardly, and abaflle arm struck up from the free end of said strip and opposite said bafflle section, a shaft journalled in said lower arm and said bottom strip, a propeller mounted onsaid shaft over said bottom strip and between said baiile section and said baiiie-arm, and vmeans on-said bracket for rotating said propeiler. i

2. A beater having, in combination, a frame, a bottom strip formed integral with saidframe, a baiiiearm struck up from said bottom strip, a propeller member mounted for rotation directly over said strip and in closely spaced relation thereto, said baiiie arm being inclined rearwardly with respect to the direction of rotation of said propeller member, and being twisted to form a rearwardly and outwardly'inclined baffle surface,

and means for rotating-said propeller.

3. A beater having, in combination, a frame comprising an integral part bent to form an upper support, a side member extending downwardly from said Support, a horizontal bottom member extending laterally from the lower end of said side member and underlyin said support, and a baiile arm struck up' rom the free end of said bottom member, a shaft journalled in said4 bottom member, a propeller mounted on said shaft over said bottom member, and means on said support for rotating said propeller.

4. A f beater having, in combination, a framemember comprising a bar bent to form a central member, a depending side member inclined from said central member and form-` ing a baile section at its lower end, a horizontal bottom strip, and a baille arm struck up from the free end of said strip and opposite said bafiie section, a shaft journalled in said central member and Said bottom strip, a propeller mounted on said shaft over said bottom strip and between said baiiie section and said baiie arm, and means forlrotating said propeller.

5. A beater having, in combination, a stationary frame, a curved bottom strip formed integral with saidframe and being concave upward, a. shaft rotatablev in said frame, a propeller member fixed on said shaft, baie means extending up fromsuid bottom strip, and means for rotating said shaft. f

6. A beater having, frame, a bottom strip formed integral with said frame and having a free end ka shaftrotatable in said frame, a propelier member fixed on said shaft and having vanes inclined upwardly and forwardly to force liquid downwardly Vagainst said bottom strip, a bafiie arm extending up from the free end of said bottom strip, and meansA for rotatin said shaft.v l

7. A beater having, ,in combination, a frame, a bottom strip on said frame, a shaft rotatable in said frame, a propeller member fixed on said shaft, baiiie means extending up from said bottom strip, said battle means being inclined from the vertieabund means for rotating said shaft.

In testimony whereof we have hereunto afixed our signatures.
